Yes its worth it. I'm a fairly new chickie owner. Last fall I let my broody Orpington hatch some eggs. It was a neat experience watching her raise her babies. Well late this spring she went broody again, but kept breaking the eggs so I ordered day olds. I know the standard approach for introducing them to the mom is placing them under her at night, but I picked them up from the post office at 6am and couldn;t wait that long. So I tried one at a time introducing them to her. So as I opened my hand and placed he chick near her, she did the funniest thing, her eyes got all big and clucked and tucked the baby right away under her almost like she said "oh there's my baby" and she did that with each one I gave her. She was the best mom, and even tried babing them when they were as big as she was and she had to follow them around instead of them following her. If she goes boody again this spring, I want to get more for her.
Its totally worth it, its great being able to watch the hen teach her babies new things and how to be a chickie, plus its less work for you since she does it all.
